NCL Check-In Question

[mdsgu]

So we are cruising from Stockholm to Oslo on June 5.  As per our usual, I and my father-in-law are booked into Cabin 1 and my wife, 2 kids, and mother-in-law are booked in Cabin 2.  Somehow, I'm in charge of doing all the check-in malarkey.  So I've got everyone's check-in complete except my wife and kids.  For the onboard charges, obviously they need to be linked to my credit card, but in that section of check-in, the drop down list for who will be responsible for charges only has the adults in that cabin.  I was able to link my MIL to her card, so that's fine, but how do I link my wife and kids to my card?  When I'm in another cabin?

If your wife has a card, you can link to that.  Otherwise, the easiest thing to do is just link the entire cabin to your MIL and then when you are checking in, ask them to change it.
